Making the case for the #CorsiRosenthalBox with studies.

A simple thread.
"no U.S. Energy Star certified air cleaners have CADR values (for either tobacco smoke, dust, or pollen) matching the CADR value for the CR Box even on low speed "

On cost? 1/10th.

1019 to 1444 m3/hr CADR.

(600 to 850 ft3/min)

Published here:
tandfonline.com/doi/full/10.10… ImageImage
An incredibly thorough study published in February 2023, with all of its authors from @NIOSH.

With universal masking in a 3-ply cotton mask, exposure to the relevant aerosol size is reduced by 88 to 94%, with the #CorsiRosenthalBox.

73% w/ CRBox alone.

sciencedirect.com/science/articl… ImageImage
Very good thread on this study here:

Essentially the same NIOSH team investigated HEPA efficacy.

65% reduction with HEPA alone.

So, at a much cheaper price, the #CorsiRosenthalBox gets better results.

cdc.gov/mmwr/volumes/7…
But can HEPAs remove SARS-COV-2 from the air? Yes.

(Would #CorsiRosenthalBox do the same? Yes - faster and cheaper.

Has it been studied specifically for this? No. HEPAs barely have.

Do the same laws of physics apply? Yes.)

journals.asm.org/doi/full/10.11… Image
But can HEPAs really remove SARS-COV-2 from the air?

Yes - in a UK hospital, HEPAs were off. Cov1d was in the air. Turned on. No more CoV1d.

1000 m3/hour CADR.

Remember the first study?

1019 to 1444 m3/ hour for the CR box.

@MarinaC_Dyb and her fellow authors found a massive reduction in aerosols in OCCUPIED classrooms using the #CorsiRosenthalBox. Also found that ALL of the air went in.

No wonder they have rolled them out to 400 locations.

Oh for Pete's sake. @elonmusk has just killed another thread.

Let me add these manually.
"Also found that ALL of the air went in" - quoting above to go into a little more detail:

This answers, in a study, the concern that it just moves the air around. That it won't go into the filter.

It does, and this had to be pointed out.
The CDC, of which NIOSH is part of, has officially recommended 5 ACH, minimum, and that DIY Air Cleaners are effective at reducing the risk of transmission of Cov1d.

The #CorsiRosenthalBox is
specifically mentioned as part of that solution.

cdc.gov/coronavirus/20… ImageImageImage
@3M has studied it in their formal lab - and is officially on board:

news.3m.com/2022-02-24-3M-…
The famous UL, Inc testing the safety of the #CorsiRosenthalBox, to make sure it won't catch on fire.

It won't - even if the filters are loaded up.

(The link that is out on Twitter appears to be dead.)

"Does Using Corsi–Rosenthal Boxes to Mitigate COVID-19 Transmission Also Reduce Indoor Air Concentrations of PFAS and Phthalates?"

Yes.

pubs.acs.org/doi/10.1021/ac… Image
Some have expressed surprise that this was found.

Dr. Corsi explains:

And the rest of your family?

A thesis - a study, that found 7 PFAs, and exposure to for both dog and human. (@ShellyMBoulder collaborated).
elischolar.library.yale.edu/ysphtdl/2161/ Image
How do we know that dogs are affected? Because it is dogs that get experimented on.

And not to get too personal, but my dog has stage 4 chronic kidney disease. CKD can be caused by PFAs.

Did I do that? Or at least not prevent it? A lot of

years with no air filtration.

But hey - she is 15 years old, and it could be just old age.

In any event, I don't want to go into any more detail, but now I know better.

But besides PFAs, dogs can catch Cov1d.

As can cats.

In fact, from the study, we should see our cat as part of our family regarding virus transmission.

Can a cat or dog wear a mask?

Yes, with training.

But what if you could reduce their risk of catching Cov1d without all that? Image
And the risk to the rest of your family?

30 case studies- oops, 30 of your stories here, where your family used the #CorsiRosenthalBox as the centerpiece of your family pandemic prevention protocol.

And it worked.

🔥 Wildfire season, folks! 🔥

Got a smoky or smokey house from a fire or a BLT sandwich gone wrong?

TLDR;
Make a #CorsiRosenthalBox with activated carbon filters

AND CLEAN SURFACES:
By vacuuming, dusting; then wiping and mopping with a commercial, non-bleach solution. Pic of smoke and fire - hopefully not headed your way.
Huge caveat. The carbon filters will fill up quickly with particulate matter.

While the smoke is ongoing? Regular filters.

After the smoke is over, while cleaning up? The activated carbon filters (ACF).

Someone is working on a variation of the CR Box w/ 3 regular panels,
1 ACF panel. Numbers are still being run. No ETA, so I am going forward with this thread, as is.

⚠️ACFs are also great for paint fumes.⚠️

BTW, this thread will get a fair amount of useful clarifications, so check the end of the thread, in a couple of days.

A new strategy.

I used this new study, that points to C0vid co-infection with StaphA, worsening StaphA, to write the HICPAC.

The patient safety pages do not recommend N95s.

This allows me to avoid the quarrel of StaphA OR C0vid being airborne.

And allows me to use their words on N95s being best for C0vid against them.

Soft-copy email below.

hicpac @ - just join these together.

This strategy can be used on every safety page for every disease.

Find the X CDC safety page. Confirm no N95s recommended. They never are.

And you are off to the races.

Some will think, "this is just some weird internet trick."

This is just us using their system against them.Scholar.google.com

A NEW Colorado Chicken farm outbreak with 1.34 million.

The one with 5 people confirmed infected, 64 pending, has 1.8 million, 10-14 days of work.

CDC team of 10 has just been dispatched for the 1.8 million.

The farms are about 35 minutes apart (thank you @0bFuSc8!)

Holy airborne H5N1.

69 symptomatic workers, 5 positive so far?

150 on antivirals?
It's always been airborne.

This means that it is more transmissible to the humans than before.

Not Covid levels. Probably not even original WT level.

But more transmissible to the humans than before.
Homeland Security moved to Level 2.

I get it. You need a place to decompress.

So, the Covid Careful tend to take umbrage to outdoor transmission studies.

Outdoors IS safer. But study after study has shown outdoor transmission.

As do these 2 studies.

Catching Covid Camping.

I deliberately began this thread with white men, because the only countries doing these detailed studies are Asian countries. As is this one.

But every time, a tinge of ethnocentrism creeps into replies. Please keep this in mind :) .
Many don't know that measles is airborne outdoors based on an hour long conversation with a young boy and his family, after the Special Olympics. No CCTV. No credit card tracing. No GPS.

Our first study? July 24–26, 2020. South Korea. South Korea had done an

Great summary below. Some important info not discussed by Dr. Hirschson.

This study adds to RECONFIRMING H5N1 is airborne.

Since seeing is believing, you are one of the VERY FIRST to see what H5N1 aerosols do to a cow lung.

🧵

This study is by the USDA.

As I have, & will continue to point out, @nirav_uscdc, they continue to ensure dairy workers are NOT told to wear N95s. Or PAPR as indicated would be more comfortable by @RanuDhillon @sri_srikrishna.

But worn here in their lab. By them.

Aerosols, 3-5 microns, were nebulized into the cows nostrils.

Correction to the study...SOME of those that size will deposit into the Lower Respiratory Tract. Not all. Some will deposit into the Upper Respiratory Tract.

Some will be exhaled, and inhaled again.
